FLIER.

Original application filed. March 19, 1924, Serial No. 700,390. Divided and this application filed July 3.

This is division of my copending appli= cation on a method of making fliers, flled March 19, 192 1, Ser. No. 700,390.

This invention relates to a flier for a tea tile machine capable of being made out of a single piece of metal and by means of metal pressing and rolling operations.

The principal object of the invention is to provide a perfectly balanced and accurately constructed flier that can be manufactured from a flat blank of metal. The invention also involves improvements in the balancing rod of the flier, the provision of the thread guide in the right shape so that the center or crownof the flier can be formed by simple metal pressing operations from the same piece of stock and then curved to bring the thread guide and balancing rod into parallel position.

Other objects and advantages of this invention will appear hereinafter.

Reference is to be had to the accompany ing drawings, in which- Fig. 1 is a full size side View of the completed flier;

Fig. 2 is a sectional view of the same, on the line 2-2 in Fig. 1;

Fig. 3 is a fragmentary plan of the same looking in the direction of the arrow 3 in Fig. 1;

Fig. 4- is a fragmentary side view of the san e showing parts of the device in central section;

Fig. 5 is a View of the bearing taken out of the flier;

Fig. 6 is a sectional view on the line 6-6 of Fig. 5; and

Fig. 7 is an edge view showing the thread guide of the flier after the same has been twisted to throw the thread guiding slot out of a straight line.

The completed flier is made by the method disclosed and claimed in my original ap plication above identified. It comprises a crown or center C having a boss 0 at the iottom screw-threaded inside to receive the stem F. This stem constitutes the only part of the flier that is not integral throughout. On one end, this flier has a balance rod a Serial No. 41,382.

which is elliptical in cross-section and parallel with it is the thread guide I) which is hollow and tapering, being formed from the same piece of sheet metal as the balance rod. This thread guide has a slot 5 extending along it, the two ends of which are parallel and aligned as indicated and which is offset at b by holding these two ends and twisting it a point below the center. Also located along the thread guide are two integral projections B separated by groove E which is merely a continuation of the cylindrical or convex shape of the thread guide. These projections are formed integral without any openings through them. They constitute a guide for the end ring of the presser.

The stem F is provided with a transverse perforation f and a pin G is inserted through it to engage the threads of the hub 0 and hold the stem in position. In use, this is carried on a spindle having a groove or notch for receiving the pin G. Inside the hub 0 is threaded for the reception of the threaded partof the stem F. This stem is properly finished to furnish the bearing of the flier and properly located so that the rod a will balance the thread guide Z).

In this way it. will be seen that a complete flier is produced. all of it except the stem F being formed of a single piece of metal, operated on by various tools in the process but coming out in a uniform condition not requiring any machine finishing of any kind and perfectly balanced b cause after the tools have been once designed correctly, they will manufacture hundreds of thousands of these articles just alike. The hand work being eliminated, particularly the delicate balancing of the device, the cost of production on a large scale is very greatly reduced.

Although I have illustrated and described a particular form of the invention I am aware of the fact that departures can be made from the exact form described Without departing from the scope of the invention as expressed in the claim. Therefore I do not wish to be limited in these respects but what I do claim is As an article of manufacture, a flier for therewith, and extending parallel to the thread guide, said crown, thread guide, and balance rod being metal.

In testimony whereof I have hereunto atflXQCl my signature.
